The Golden Thread – Lifecycle of a Fire Door

Fire doorset legislation has changed significantly in the recent years, with changes made at every stage in the lifecycle of a fire doorset, from design & testing to inspection & maintenance. For social housing fire doorset specifications, this means that all the stages in the lifecycle of a fire doorset, need to not just be included in the specification, but reviewed to ensure compliance with the new legislation.

One of the most important changes to legislation is The Golden Thread, created to link all stages in the lifecycle of a fire doorset. It is required for all high-risk residential buildings (HRRBs) to ensure that the original design intent of the fire doorset is preserved, that any changes must be made through a formal review process and the data for lifecycle is visible to responsible person(s) and tenants.

There are five steps in the lifecycle of compliance for a fire doorset, with the first step (Design & Test) being the key reference point for all other steps to ensure the original design intent is preserved.

It is of paramount importance that maintenance teams are fully trained and have knowledge of the individual aspects of a fire doorset. This should include, tested performance knowledge and product composition to ensure what was tested is the same as what is surveyed, manufactured, installed and maintained.

As an example, if a fire doorset has a damaged or broken piece of glazing, the maintenance team will need to have been trained and have the knowledge of how the doorset was constructed. They must be able to replace components like for like and know what components should be replaced as part of this repair. This will ensure the fire doorset remains compliant and its performance is maintained as per original design intent. For example, how will a non-trained maintenance team be able to know the type of glass required to carry out a repair?

We are seeing an increasing number of report cases where components are being replaced during maintenance with components that are not part of the original test data and even where non-fire rated components have been used.

When specifications are changed and aren’t reviewed to ensure compliance with legislation, this brings significant personal risk to you as the responsible person(s). Under the new legislation the responsible person(s) is both legally and financially at risk if The Golden Thread is not adhered to at every stage of the lifecycle.
